UPDATE: Rhett Reese, who co-wrote the first Zombieland with his writing partner Paul Wernick, has taken to Twitter to calm everybody's nerves:
Don't believe all the articles. We will be returning to Zombieland.
A few months ago Zombieland 2 seemed like a sure thing. They had at least a first draft of the script done and there were even rumors that writers Rhett Reese and Paul Wernick were courting big names to fill the movie’s obligatory, big celebrity cameo. But now Zombieland star Jesse Eisenberg is an in demand star in Hollywood, with a lot of other offers, and the film’s director and writers have gotten busy with other projects. Even Woody Harrelson, who played Tallahassee in the film, is starting to talk as though he thinks the whole thing is a bad idea.
Talking to Total Film about the proposed Zombieland sequel Harrelson says he isn’t so sure he wants to return to that world. He explains, “I'm sure it will happen if everyone does it, but I'm not sure it's the right thing to do.” As one of the “everyones” who would have to do it, whether or not he thinks it’s the right thing to do is sort of important. And Harrelson says, “I don't feel like a sequels guy.”
Woody’s talked openly about how great he thought the first movie was, so why wouldn’t he want to do another one? He explains, “It's one thing to do it when it came out real good and it made a lot of people laugh, but then to do a sequel... 99 out of 100 are worse by a lot. So I don't know.”
Things don’t look good for Zombieland 2. Till now Harrelson had seemed like the most likely member of the cast able to clear out enough time in his schedule for a return, if they can’t even get him on board, there’s probably not much hope for this project.
